The PR firm engages honestly with the journalist: "here is an article about how suits are back and calls out my client's suits as being particularly popular right now."

(i.e. it is a thinly veiled ad for their client)

If the journalist blindly publishes this, they are being dishonest with their readers who might assume (especially 20 years ago) that this was an unbiased article, based on the journalist's own research.
